BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox paniculata, typically grown as a container and garden Phlox, hereinafter referred to by the name ‘IFPHLFM’ and disclosed in U.S. Provisional Patent Application Ser. No. 62/764,553.

The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Andijk, The Netherlands. The objective of the breeding program is to create new vigorous Phlox plants with numerous attractive flowers.

The new Phlox plant originated from a cross-pollination of a proprietary selection of Phlox paniculata identified as code number 9009-05, not patented, as the female, or seed, parent with a proprietary selection of Phlox paniculata identified as code number 047-11-K013-01, not patented, as the male, or pollen, parent in August, 2013. The new Phlox plant was discovered and selected as a single plant from within the progeny of the stated cross-pollination in a controlled nursery environment in Andijk, The Netherlands in July, 2014.

Asexual reproduction of the new Phlox plant by cuttings in a controlled environment in Andijk, The Netherlands since September, 2017 has shown that the unique features of this new Phlox plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Phlox plant has not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘IFPHLFM’. These characteristics in combination distinguish ‘IFPHLFM’ as a new and distinct Phlox plant:

-   -   1. Compact and uniformly mounded plant habit.     -   2. Moderately vigorous to vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Flowers that are intense red purple in color.     -   7. Good container and garden performance.

Plants of the new Phlox and the female parent selection differ primarily in flower color as plants of the new Phlox have red purple-colored flowers whereas plants of the female parent selection have light purple-colored flowers.

Plants of the new Phlox and the male parent selection differ primarily in the following characteristics:

-   -   1. Plants of the new Phlox are not as compact as plants of the         male parent selection.     -   2. Plants of the new Phlox have larger flowers than plants of         the male parent selection.

Plants of the new Phlox can also be compared to plants of Phlox paniculata ‘Barfourteen’, disclosed in U.S. Plant Pat. No. 12,605. In side-by-side comparisons, plants of the new Phlox and ‘Barfourteen’ differ in the following characteristics:

-   -   1. Plants of the new Phlox have larger flowers than plants of         ‘Barfourteen’.     -   2. Plants of the new Phlox and ‘Barfourteen’ differ in flower         color as flowers of plants of the new Phlox are lighter red         purple in color than flowers of plants ‘Barfourteen’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Phlox plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phlox plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘IFPHLFM’ grown in a container.

The photographs on the second sheet are close-up views of a typical inflorescence (upper photograph) and typical leaves (lower photograph) of ‘IFPHLFM’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 17-cm containers in an outdoor nursery in Heerhugowaard, The Netherlands and under cultural practices typically used in commercial Phlox production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 4° C. to 15° C. Plants were pinched five weeks after planting and were 15 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
